Will Poor Cleaning Of Fan Coil Units Threaten Health?

The fan coil units of central air conditioning should be cleaned and maintained regularly, no matter in winter or summer. Because the fan coil units run for a long time, there will be a lot of dust in the tuyere. If the fan coil units are not cleaned and maintained regularly, the service life of the fan coil units will be affected. If the cleaning is not clean, it will also affect the health.


据美国环保局、丹麦技术大学等机构在美国和欧洲的调查结果显示,中央空调通风系统由于长期运行、清洁不当等原因,室内空气污染来自于空调通风系统的占42%--53%,通风系统内主要污染物为颗粒物和微生物。都是用眼睛看不到的所以在清洗时一定要认真仔细。

According to the survey results of EPA and Danish University of Technology in the United States and Europe, 42%-53% of indoor air pollution comes from air conditioning and ventilation system because of long-term operation and improper cleaning. The main pollutants in the ventilation system are particulate matter and microorganisms. You can't see them with your eyes, so you must be careful when you wash them.


中央空调风机盘管系统承载着现代楼宇的空气新陈代谢,是楼房内名副其实的核心器官――“肺”。

The central air conditioning fan-coil system carries the air metabolism of modern buildings, and is the core organ of the building - lung.


中央空调的通风系统是长期积累下来的卫生死角,其面积远大于我们平时能够清洗到的机组面积。

The ventilation system of central air conditioning is a long-term accumulation of sanitary dead angle, its area is far larger than the unit area that we can usually clean.


虽然长期清洗,但是清洁不干净,得不到清洁的风管为有害物质提供了安稳的环境,它们会不断滋生并随着四通八达的通风管道在室内广泛传播,在空调内部造成空气二次污染,建筑物空调通风系统所造成的人体健康危害和疾病可达几十种。根据其对人体的危害程度、疾病的性质、致病的病原大致可分为三大类:急性传染病(如军团病、SARS);过敏性疾病(包括过敏性肺炎、加湿器热病等);“病态建筑综合症”。

Although long-term cleaning, but not clean, not clean air ducts provide a stable environment for harmful substances, they will continue to breed and spread widely in the indoor with all kinds of ventilation ducts, causing secondary air pollution in the air conditioning, building air conditioning and ventilation system caused by human health hazards and diseases. Up to dozens of species. According to the degree of harm to human body, the nature of the disease and the pathogen of the disease, it can be roughly divided into three categories: acute infectious diseases (such as Legionella disease, SARS); allergic diseases (including allergic pneumonia, humidifier fever, etc.); and "sick building syndrome".


用显微镜分析从中央空调通风系统内采集的粉尘样本得知,它的主要成份为尘土沙砾、炭类物质、结晶体、纤维、涂料片、腐蚀掉落风管内壁材料等,此外还有一些昆虫的尸体混杂在其中。一旦灰尘当中附着有细菌、真菌、酵母等微生物时,也就很容易使人患过敏或是呼吸系统疾病。

The dust samples collected from the central air-conditioning ventilation system were analyzed by microscopy. The main components were dust gravel, carbon substances, crystals, fibers, coating sheets, corroded materials on the inner wall of the falling duct, etc. In addition, some insect corpses were mixed in them. Once there are bacteria, fungi, yeasts and other microorganisms in the dust, it is easy to cause allergies or respiratory diseases.
